Solution Overview
Problem
The decreasing space for physical buttons in vehicle display apparatuses due to increasing screen sizes complicates user interaction, especially at high speeds, and existing solutions fail to effectively manage button visibility and usability.
Innovation Solution
A curved display apparatus with a projector, mirrors, an infrared illuminator, and a physical button layer storage device that automatically draws out or retracts physical buttons based on vehicle speed or user input, ensuring sufficient space and preventing driver distraction during high-speed travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical buttons are always visible, then user interaction reliability is improved, but driver distraction risk increases during high-speed travel
Solution Approach 1:
The system dynamically controls the visibility of physical buttons based on vehicle speed conditions. When the vehicle exceeds a predetermined speed threshold, the controller automatically retracts the button layer into the housing, eliminating potential distraction sources. When speed is below the threshold, buttons are protruding and accessible, ensuring reliable interaction when safe.
Solution Approach 2:
The controller receives feedback from the vehicle's speed sensor and automatically adjusts the button layer position accordingly. This closed-loop control system monitors speed conditions and responds by protruding or retracting buttons, adapting the interface to current driving conditions to balance accessibility with safety.
2Ease of operation
If the physical button layer is drawn out, then button accessibility is improved, but the device complexity increases
Solution Approach 1:
The physical button layer is extracted as a separate, movable component from the main display structure. It is housed in a dedicated storage housing with its own drive mechanism, allowing it to be independently controlled to protrude or retract. This separation simplifies the overall design by isolating the button mechanism from the display and control systems.
Solution Approach 2:
The button layer includes its own dedicated drive device and control logic within the housing, making it a self-contained module. The controller receives speed feedback and automatically controls the button layer position without requiring manual intervention or complex integration with other systems, reducing overall device complexity.

Data Source
AI summary
A curved display apparatus and method for a vehicle are provided. The apparatus includes a projector disposed within a dashboard and configured to project an image onto a predetermined projection area. A first mirror reflects the image projected from the projector. A second mirror reflects the image reflected from the first mirror and a curved screen of the dashboard displays the image reflected from the second mirror. An infrared illuminator outputs infrared rays onto the curved screen and an infrared imaging device captures an infrared image of the curved screen. A physical button layer storage includes a housing and a physical button layer accommodated inside the housing and is drawn out to the front of the curved screen. A controller determines a touched position based on the infrared image and determines whether a pop-up condition is satisfied to draw out the physical button layer the front of the curved screen.
